Observations

These animals have a relatively short lifespan in the wild with one study estimating an average lifespan of 1.7 years. Nonetheless, it has been reported that they can live up to 34 years in the wild [0445]. This is not impossible but questionable considering that the oldest individual in banding studies involving thousands of recoveries was 21.3 years of age [0729].
